I look around the world and see so many wonderful things that I love and enjoy and benefit from, whether it's art or music or clothing or food and all the rest. And I'd like to add a little to that goodness.

Cults and prophets proclaiming the imminent end of the world have been with us for several millennia, and it has been another sour sort of fun to ridicule them the morning after, when they discover that their calculations were a little off. But, just as with Marxists, there are some among them who are working hard to "hasten the inevitable," not merely anticipating the End Days with joy in their hearts, but taking political action to bring about the conditions they think are the prerequisites for that occasion.

There are no forces on this planet more dangerous to all of us than the fanaticisms of fundamentalism.
